Better mechanical resistance, better heat exchange and electrical insulation, allowing you to maximize the operative performance over time.

Thanks to the impregnation process of windings in the electric motors, you can get many advantages. Indeed, this procedure allows to obtain a better mechanical resistance, a better heat exchange and electrical insulation, allowing you to maximize the operative performance over time.

How is this process evolving?

If previously the impregnation was reduced to a simple dripping of resin on the winding put in rotation, now more efficient and accurate application methods are required. This is mainly due to the use of resins with ever-increasing performance and costs and the need to minimize the resin waste to avoid expensive disposal.

What are the main advantages?

In the impregnation/trickling process, the volumetric dispensing systems offered by DAV Tech allow you to manage it in a simple, precise, and easily adjustable way.

By using PCP and GP volumetric pumps, the resin dispensing is insensitive to changes in viscosity and is not conditioned by ambient temperature. Not only they allow you to change the flow rate and the quantity dosed remotely via software, but it is also possible to manage it through a dedicated drive or controller with display. The accuracy of the quantity is dispensed in the order of +/-1%. In addition, the dispensing of loaded resins does not cause any mechanical damage.
